Hardware Installation and Maintenance Guide, Version 11.50.3 - Download software files from support site

You download the ThinkSystem OS software package from the Lenovo Support Site to your management host system.

The latest ThinkSystem OS files are available on the host system where the ThinkSystem Web Services Proxy and ThinkSystem SAN Manager are running.
You know whether you want to activate your software upgrade now or later.
You might choose to activate later for these reasons:
- Time of day – Activating the software can take a long time, so you might want to wait until I/O loads are lighter. The controllers fail over during activation, so performance might be lower than usual until the upgrade completes.
- Type of package – You might want to test the new OS software on one storage array before you upgrade the files on other storage arrays.

Important: Risk of data loss or risk of damage to the storage array - Do not make changes to the storage array while the upgrade is occurring. Maintain power to the storage array.

If your storage array contains only one controller or you do not have a multipath driver installed, stop I/O activity to the storage array to prevent application errors. If your storage array has two controllers and you have a multipath driver installed, you do not need to stop I/O activity.
From the main view, select Manage, and then select one or more storage arrays that you want to upgrade.
Select Upgrade Center > Upgrade ThinkSystem OS Software.

The Upgrade ThinkSystem OS software page appears.
